In this study, we report that electrooxidation of phenolic cyclopentenedione, 2,2'-bis[4,5-bis(4-hydroxybenzyl)-2-(4-hydroxyphenyl)-cyclopent-4-ene-1,3-dione] results in the formation of nonconducting films which make uniform, defect-free and stable layers with permselective properties on gold and carbon surfaces. The electropolymerization process proceeds in neutral aqueous medium at potentials higher than +0.6 V (vs. Ag/AgCl, 3 M KCl). The polymer prepared was characterized by electrochemical methods, quartz crystal microbalance, Fourier transform Raman and infrared spectroscopies, and scanning electron microscopy. The polymeric film can be used for electrode coating and thus preparation of an anti-interference barrier, for example, in dopamine microelectrode sensor construction. The results presented here are the first evidence for the preparation of phenolic cyclopentenedione-based functional film. (C) 2013 Elsevier B.V. All rights reserved.
